1. 創建webservice,為了免于落俗我稍稍修改了創建webserice的默認webmethod。^_^
using System;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;
[WebService(Namespace = "
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class Service : System.Web.Services.WebService
{
public Service () {
//Uncomment the following line if using designed components
//InitializeComponent();
}
[WebMethod]
public string SayHelloTo(string Name) {
return "Hello "+Name;
}
}
還是俗了點。:)
2. js調用webservice+xmlhttp的實現部分。
<html>
<title>
Call webservice with javascript and xmlhttp.
</title>
<body>
<script language="javascript">
//Test function with get method.
function RequestByGet(data){
var xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
//Webservice location.
var URL="http://localhost:1323/WebSite6/Service.asmx/SayHelloTo?Name=Zach";
xmlhttp.Open("GET",URL, false);
xmlhttp.SetRequestHeader ("Content-Type","text/xml; charset=utf-8");
xmlhttp.SetRequestHeader ("SOAPAction","http://tempuri.org/SayHelloTo");
xmlhttp.Send(data);
var result = xmlhttp.status;
//OK
if(result==200) {
document.write(xmlhttp.responseText);
}
xmlhttp = null;
}
//Test function with post method
function RequestByPost(value)
{
var data;
data = '<?xml version="1.0" encoding="utf-8"?>';
data = data + '<soap:Envelope xmlns:xsi=";
data = data + '<soap:Body>';
data = data + '<SayHelloTo xmlns=";
data = data + '<Name>'+value+'</Name>';
data = data + '</SayHelloTo>';
data = data + '</soap:Body>';
data = data + '</soap:Envelope>';
var xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
var URL="http://localhost:1323/WebSite6/Service.asmx";
xmlhttp.Open("POST",URL, false);
xmlhttp.SetRequestHeader ("Content-Type","text/xml; charset=gb2312");
xmlhttp.SetRequestHeader ("SOAPAction","
xmlhttp.Send(data);
document.write( xmlhttp.responseText);
}
</Script>
<input type="button" value="CallWebserviceByGet" onClick="RequestByGet(null)">
<input type="button" value="CallWebserviceByPost" onClick="RequestByPost('Zach')">
</body>
</html>
對于使用post方法需要發送的那堆東東可以在webservice的測試頁面中找到,自己拼湊加上對應的參數就可以。
我發現用post方法的時候響應很慢,是因為用Post方法時發送的數據多的原因嗎?
